The crash was reported at 2:40 p.m. north of Laguna Canyon Road, the CHP said in a news release.

A 54-year-old Irvine woman was traveling at 60 mph in the No. 4 lane when she applied her brakes after noticing the woman in front of her, driving a 1966 Ford, was traveling at a significantly slower speed, the CHP said.

The Irvine woman wound up rear-ending the Ford, driven by the Mission Viejo woman, causing it to travel across the freeway and hit the center divider wall, the CHP said.
